How customer reviews and ratings work

Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.

To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.

4.0 out of 5 starsIt does the job I need, though sometimes it isn't obvious
Reviewed in the United States 🇺🇸 on September 12, 2018
This could be the most informative review you'll find on the Ruizu X02, 8 Gb internal memory. I give it the stars based on a comparison with other players at this price that serve this function. Maybe I'm giving 4 instead of 5 so you'll read it, since so many 5 star reviews seem so meaningless and fake. And I've not had it long enough to give an honest statement on durability. (I skip the extremes and read only the 2, 3 or 4 star reviews since they tend to be more informative. I'll use 4, even though my negatives below are really quite minor.)

I don't understand the reviews and questions by people who want a device that is simpler and less expensive than their phone, then are amazed that a player at this price doesn't do the same things as their phone or old iPod that died after a couple years. This isn't a phone. Its not an iPod. It does the job. If I get several, and each one I buy lasts 12 months, collectively they outlasted an iPod and still cost signficantly less.

I want a small, simple device to play through headphones while I exercise or lay about or drive my 2 or 4 wheel motor vehicles. I want an inexpensive player so I would not risk losing or damaging a more valuable device like my phone. And it does the job. No matter how good the headphone, I'll snag the cord on a chair or the cat will grab it, breaking the wires and needing another pair. Other pairs are easy to find, they don't cost much, and expensive ones don't last longer. For now, the ones that came with X02 are okay. They do the job.

I listen to podcasts, and sometimes selected music. Plug the Ruizu X02 cable and move mp3 files from the computer into files on the player, then turn it on and play the files. It does the job. I don't have a countless collection of music files that play for more hours than I would probably play in a lifetime that I'd want to stuff on the mp3 player at the same time to play in confusing lists or scrambled that I'd never know what is playing. I play what I want, and when my preferences change, I delete the old and put on new files. For me it does the job.

I'd not use the X02 for videos, or pictures or even ebooks. If the screen was the same size as the entire front of the device, I'd have to use a magnifying glass to see any details or get more than a couple words per screen. The screen is a good size to see what is playing or what files you are opening, so for that it does the job.

The negative is exactly what buttons do which job is uncertain. Apparently, there are different versions of Ruizu players with the same model numbers, and I've seen different sellers with minor variations all implying they made the players. And yet, the same brands and model numbers have slight differences. You can see this in the reviews by verified buyers. Even the sellers don't always know exactly how the buttons work on the variety of phones that all say Ruizu x02. If you aren't willing to spend a little time pressing and/or holding different sequences of buttons to see what happens, you might give up. For example, to restart the player later on where you left off, you need to go to sleep mode instead of turning it off. The directions and other users say press and hold the button in the center of the dial to sleep. I do it and mine goes to "easy" mode. I like easy mode when I'm using it, but easy isn't sleep. I see this in the answered questions on Amazon. I asked online, and the seller says press and hold the center button. That didn't help. I experiment. I learned. I now press and hold the volume button at the bottom of the outer dial. When the volume slider shows, I press and hold the center button and it goes to sleep. In easy mode, I just mash the top or bottom of the outer ring and the volume slider appears, then press and hold the center button. It took a bit of time, but I finally found the sleep mode. And the player does the job.

I listen to the podcasts during morning exercise, the drive in to the office, and the drive home, I might play some music later while reading, then load in a new collection of podcasts before going to bed. For what I need, it does the job. And by having this item, I don't do things with my phone that might cause me to damage or lose it.

One thing the X02 lacks that I'd like in something this small is a hole through the same edge with the headphone plug, a clean hole that comes out nearby in the back. A hole like that is common in many other players, and I would thread in a lanyard that I could carry around my neck for the times my shirt doesn't have a pocket. And even when my shirt has a pocket, on a lanyard it won't fall out and yank on the headphone plug in a way that kills the player. Well, no big deal. Not all mp3 players have it. If that becomes important to me, I have superglue gel and a jump ring, a method I used before. For now, I use a 1930s hidden carry derringer shoulder holster that my nephew played with when he wanted to pretend he was a secret agent. If you don't have one, a cheap grouch bag or neck-carry sunglass case would work, too.

Later tonight, I'll load in more podcasts.

2.0 out of 5 starsThese Are Not Built To Even Chinese Standards.
Reviewed in the United States 🇺🇸 on April 4, 2019
This guy looked exactly like an AGPTEK down to hand feel, whatever freeware Chinese operating system all these generic mp3 players seem use, and all its other features.

In terms of usage, it worked the exact same as an AGPTEK, the OS even started up the same as them and the layout and even icons were the exact same as them. The volume control wasn't as intuitive so I'd have to ding it there, and I can't speak for the battery life, but the battery certainly didn't agree with the claims considering my commute to and from work drained it nicely, but that could be attributed to the aux cord pulling extra power since I like blaring it. I'd comment more on the battery life, but unfortunately I didn't get full use out of it. It has nicer weight distribution compared to an AGPTEK and the sound quality might be slightly better, but it's certainly not worth the extra $10+ dollars that could be used towards better features.

Now for the hardware, which is the meat of the issue and why I gave this two stars instead of three. Every mp3 player I've had will eventually get the "washing machine test," that is, I bring it in from my truck with it in my jean pockets, forget about it, and send it through the washer and dryer. The only component on any mp3 player that should be affected by this is the pillow supercapacitor (that big grey thing in my picture) which is sensitive to moisture. The dry cycle on a dryer is more than enough to dry it out, and generally doesn't get hot enough to actually damage it, and an mp3 player of any size should be able to handle the beating of being tossed around in a drying machine with relative ease- you might get a shorter battery life because of the pillow cap being exposed to water, but as long as it's dried properly (and you don't turn it on while it's wet) it won't actually -damage- the thing. Obviously this RUIZU didn't survive my washing/drying machine or I wouldn't be taking it apart to see what's up. First thing I noticed when I snapped the cover off was that the soldering on this thing is crap, it doesn't even meet Class I standards which was designed for cheap Chinese electronics. I know it was sealed well because if it wasn't, the flux all over the board would have been removed by the detergent/water. In fact it's probably there was a lot more flux residue on the board. It doesn't smell nor feel like no-clean flux, so that alone means they probably used water soluble flux and didn't clean it. What that means in laymens terms is that this thing will corrode to hell within a few weeks or months tops, and surely won't last more than a year unless you're lucky. Some of the hand-soldered components are super uneven or even just globbed on there in such a way that a strong shock would knock it off, and that doesn't even begin to mention the loose solder globs on the board or the fact that they had to apply additional masking because whoever soldered the power wires BURNT the board while doing so. That kapton tape is not an effective adhesive for more than masking or temporary application, so I was pretty disappointed that they couldn't even afford a cheap adhesive to connect the power wires to the pillow cap. I can see how they were using a longer/slimmer model and hence they used a strangely shaped pillow cap/"battery" on it, but I'd have preferred if they put it, the part that gets hot, somewhere away from the screen they adhesive attached it to, probably the only part on the board that's temperature sensitive. The SMT work seems alright so I can't comment there, but there was clearly a resistor that was corroded and there was FOD EVERYWHERE on the board. I might be able to claim "well that got in with the dryer" but when there was that much flux on the board after going through my washing machine, there's no way that was lint or something from my drying machine. I mean come on, sending the boards through a washing machine and shoving it in the oven for an hour at low temperature would even be a bare minimum standard better than what I'm looking at. This is disgusting and at a level that long passes "cheap Chinese junk" and enters into pure and possibly intentional/malicious negligence. When you're selling these things for more than an AGPTEK, I expect at least a class I solder job on it. As a side note, red boards are supposed to denote prototypes, not live production models, so that's also a little concerning albeit I can live with that. If it was at least semi-clean and if there was some kind of quality control on RUIZU's end I could still justify a 3 star rating, but after looking at this I just can't justify giving it even that. I think 90% of the problems that customers experience with this thing are precisely because whoever they have soldering these things isn't doing a proper job of it and there's no quality control at all on the manufacturer's end (or if there is, they're certainly letting issues visual with the naked eye past, let alone something an AOI process would catch).

For those who don't get the technobabble; I bought it, didn't get through one battery cycle while watching it drain faster than it was supposed to, and it wasn't powering on after going through the washer/dryer (unlike every other mp3 player I've owned to date) so I tore it apart and found out it was extremely unclean inside. From what I'm seeing without even taking out the screws and looking at the other side, this thing is designed to fail within a few months and I think it's insane that it's even listed as an "Amazon Choice" when there are cheaper models that I know for a fact from taking those apart intentionally or unintentionally that they are in better condition than this.

3.0 out of 5 stars Not so good for my purposes; overall good value for hardware but bad value for software
Reviewed in the United States 🇺🇸 on January 17, 2019
Color: BlackCapacity: 8GBVerified Purchase
I've had this player now for about a year, so I know what it can and cannot do pretty well. I also work in technology, so I'm fairly well versed in standard conventions for firmware on a variety of devices. I keep it connected to power all the time, so I can't speak to the battery life, but I have a specific use case for this player and it fails miserably. I hoped to connect it to my stereo via 1/8" aux plug to RCA jack converter, then insert different 4 to 8 gb cards with different genres of music on them and switch them as my preferences change. This way I'm not leaving an expensive player or a smartphone out for my kids to break. There seem to be multiple versions of the 02 player model out there as some reviewers complain that the songs don't play in order so perhaps the software varies when the player was made. In any case, I can vouch for the fact that the software is quite terrible. The hardware feels pretty solid for a $25 player and it would be a good choice for someone taking a player to the gym or running and doesn't want to risk dropping or losing their smartphone. Provided you use it often, you can generally get the hang of the controls and strange navigation, but it's difficult to just pick it up if you've been using systems with normal button (forward and back) navigation and then pick this up to change the volume, which involves multiple button presses in the same repeated direction and only if there is music playing. Just getting back to the main menu while keeping the music playing as I write this review is near impossible.

I have never tried to play a video, but with a 400x240 monochrome screen, I can't imagine I'd have any video that could be seen well, if at all. The audio quality is above average for clarity even using mp3s that were ripped at a variable bit rate (128 kbps to 384 kbps). It's loud enough for most uses, but might not be loud enough if you're trying to hear it over loud industrial sounds like in a factory, at an auto race, etc. It would be great at the price for those high risk environments, though, considering the fairly low $25 price tag.

My biggest issue is that it doesn't stay on the shuffle mode feature. I can set it but after a few hours, something resets and, despite it still playing the same music, it somehow forgets it was shuffling. That means that if I have a song with multiple versions or live versions, it plays the same song over and over. For example, I've got a Jimmy Buffett card in there right now and I've heard five straight renditions of "A Pirate Looks at 40." Imagine that with the Christmas music card I had in last month and got to hear twelve different artists cover "Jingle Bells" in an hour. Maddening. The firmware is also set up to move the cursor controls up at times to progress and other times moving up just moves the cursor to the right. There is no logical time when you can know whether you should move the selection button up or to the right, so you have to guess, which also means you have to guess whether down or left will undo the selection you just made. One look at the tiny thin manual and you'll figure out just how functional you can expect this item to be as it's written in the very finest Engrish translation. If you can "set it and forget it" this item will have some use, but the resetting of the shuffle function makes me think that there could be other problems in the firmware that will remain unfixed as well. At least the unit has a microUSB port for power and a 1/8" aux jack along with a good 'ol power toggle. Yes, sometimes you might struggle to tell if the unit is powered on or off due to the power management feature. I would not recommend this unit for anything other than playing mp3s, whether music, audio books, or podcasts and the latter I would only recommend if you're changing out a microSD card. Transfer time on the unit (despite an alleged microUSB 2.0 port) through both Windows and Ubuntu Linux is painfully slow.

2.0 out of 5 stars Good But, Extremely Difficult to Get Around - NOT Intuitive
Reviewed in the United States 🇺🇸 on April 21, 2023
Color: BlackCapacity: 8GBVerified Purchase
Ruizu 8gb, SD cards do work. I limited mine to 32g SanDisk Class 4, I add music using PC and Eject the disk b4 disconnecting. This is old style technique that works, so far. I have several (6+) DEAD Sansa players that just sit Refreshing Data. Player works really good & battery lasts a long time, BUT, the Menu is Very Difficult and NOT like any other device. To go Up or Down use Left & Right buttons, WHY? Multifunction Buttons do not work as Described in brief manual. Heaven help us, if you want to change Albums or Genres or worse, if u want to switch between Internal vs SD. Very FRUSTRATING!!!

3.0 out of 5 stars NICE LITTLE DEVICE.... - But WHERE'S THE BLUETOOTH???
Reviewed in the United States 🇺🇸 on November 16, 2022
Color: BlackCapacity: 16GBVerified Purchase
PURCHASED NOVEMBER, 2022...

Compact & Light MP3 player to listen to my music on the go.
Sound quality was pretty good... and would probably sound even better with a quality pair of headphones.

Gave this 3 stars. - I didn't give it 5-stars because it doesn't have BLUETOOTH cabilities.
But, other than THAT... it meets my needs.
It's also expandable with a SD card.
__

CON: The unit DOESN'T have BLUETOOTH?
There is NO mention of it in the USER MANUAL, or in the DEVICE itself.

The device itself is great... but, NOT having BLUETOOTH and being to connect my BLUETOOTH speaker was a BIG disappointment. - Thus my rating of three-out-of-five STARS (3/5 stars)!!!

1.0 out of 5 stars Misleading Warranty
Reviewed in the United States 🇺🇸 on January 8, 2019

<Updated review April 2019>
I ordered this mp3 player in January 2019. In March (2 months later) it broke in a weird way - the middle circle went up underneath the screen. We were able to get the circle back where it needs to be, but the device is now unusable.

On March 13th I sent an email to the company asking for a replacement, because the warranty states, “All of RUIZU products have 1 Year Warranty for any quality problem. RUIZU promises free replacement or full refund within 12 months”.

I heard nothing back from the vendor. I sent a follow up email on April 2nd asking the status. They said that they just needed the order number and also said, “All our products with 12 months warranty, so please don't worry, we will always be here for you”

The catch? You have to leave them a good review before they will send a free replacement (even though the warranty specifically states “free replacement or full refund within 12 months”). These are their exact words in response to my email:

“The way to help you solve the problem is : you should send back the mp3 player back to our warehouse, and we will help you fix the mp3 player. But it will take much long time, and also it will take your extra cost for the shipment to our warehouse.   so we have other easy way for you to save the cost. 

The other way is: if you could leave a happy review for this product, and send back the screenshot after you leave the review, we will send you a new one for free.   if you do not happy with this request , please accept my sincerely apologize. and we will following the regular way.”

Not a vendor I want to deal with.

***original review***
I am a bit frustrated with this device, because it doesn’t have a lot of the information I would have liked in the description, and I made assumptions that weren’t accurate. I would give it 3 1/2 stars, but am giving it 4 stars because it was relatively cheap.

DEVICE: very light, feels cheap, but small enough to fit in your pocket

DATA: I have a mac and it just shows up as a separate drive. Very easy to connect and transfer data.

GAMES: There are games on this device (Tetris, Sokoban, and Snake) that can’t be removed. They are in the “Tools” section with the date/time options.

E-BOOKS: supports .TXT files only. The screen is roughly 1.25”x1.25” so there isn’t much text that can fit on the screen at a time. You can set bookmarks, but they only seem to work if you don’t exit out of the book (which you have to do to access the other features such as music, etc). Once you exit the book it removes the bookmarks. I haven’t contacted the company about this to see if there’s a way around it or if it’s a technical error, but that’s my initial discovery.

VIDEOS: supports .AVI or “160*128 AMV (converted video)”.

RADIO: pretty easy to configure. Headphones are required to make it work, as they are the antenna. It has a “clear preset” option and a “save” option, so I’m assuming you can set your own radio stations - haven’t tried this much.

MUSIC: it is very basic, so there are no sorting options, but it is easy to move songs from your computer to the device. You are limited to 3 playlists. You can’t rename them, and can only add songs to them from the device itself, not your computer.

Overall decent product

3.0 out of 5 stars Decent enough

This MP3 player is good enough for the purpose, especially for the price, but it does fall short of some standards. Yes, it plays music, and it does the job well. Its built-in FM radio is equally adept to the task, and, in fact, is one of the best FM radios I've seen in an MP3 player. It also has a photo viewer, video viewer, and e-book reader, but I haven't had any need to explore those features. While it is expandable with a microSD card, the player's capacity seems to be limited to 4000 songs unless you manually trudge through the individual folders and files on your card, bypassing the "random play" function, which would, I assume, be the most useful to most people. Workarounds could include taking the time to create playlists or move favorite songs into an individual folder for you to find manually on the player, but it would certainly be nicer to simply press "random play" and be done with it for ALL my songs, not just the first four thousand. The fact that the volume control is accessed by pressing a button first to access the control is a bit off-putting, especially when you need to make a quick volume change. When I was setting it up for the first time I accidentally locked the keypad by a bizarre combination of buttons, and it took about 10 minutes before I could unlock it again despite following the included instructions to the letter. Perhaps the worst fault of all, however, is that the power switch erases the microSD card's listing from the memory, meaning you have to rescan the card every time you turn it on, with the exception of going through your folders manually as I previously described.
This is a decent MP3 player for a low price, but it is certainly not the best player that could be found, even on a budget.

1.0 out of 5 stars Gutter trash e-waste non-product
Reviewed in the United States 🇺🇸 on May 17, 2023
Color: BlackCapacity: 8GBVerified Purchase
This product made me an environmentalist. This device's plastic and metals would be put to better use in my bloodstream, because it would shorten the suffering I endure from knowing this is a product that is produced. Quality and service this poor should be a crime. 1/5 is dishonest, as it implies 20% valuation by some conceivable human metric. Trash fresh off the assembly line, imported by wasting people's time, natural resources, and patience. My disgust in this product has driven me to cancel Amazon Prime, due to my new perception on how desperate this storefront is for money unearned, and products advertised in such a brazenly false manner. My first review to my knowledge, and hopefully my last. Never take a chance with tech devices. I thought $30 wasn't going 'too cheap' yet I was proven wrong in the world's most mundane, over-effort prank ever commited. I paid $30 to throw a chinese laborer's trash away for him.

3.0 out of 5 stars Inexpensive. Good sound quality, terrible user manual, interface that takes getting used to.
Reviewed in the United States 🇺🇸 on October 24, 2018
Color: BlackCapacity: 8GBVerified Purchase
I have to say that the user manual is the main problem. It lacks detail, particularly about problems you might encounter. It's loaded with typos and grammar errors and is obviously an imperfect translation from another language. One example among many is that a section is titled "Date Transfer" when what is obviously meant is "Data Transfer." The typeface is near-microscopic... it's like trying to read a credit card privacy statement. I had to use reading glasses AND a magnifying glass.

I had a bit of difficulty transferring my music files to the player. This was partly the fault of iTunes (don't get me started). Once I got the data transferred I could not find it on the player! There is nothing in the user manual telling you to look for the music in a "folder." I can play the music now after opening the folder, but I have to perform this step every time I turn the player on. How do I get the music out of the folder? No idea. Nothing in the manual.

With the SD card inserted, the device shows up on my desktop as two separate disks. Which is OK, except that when you eject one of the disks, the other one ejects too, prompting a warning that you have disconnected the device without ejecting a disk. Am I damaging files? No idea. There is no way to properly eject both discs that I have found.

On the positive side: the sound quality is good and their on-line support was prompt in replying and somewhat helpful. It would not have been needed had the manual been more useful.

Mike Pickett
2.0 out of 5 stars Lacks some critical base mp3 player features
Reviewed in the United States 🇺🇸 on March 1, 2019
Color: BlackCapacity: 8GBVerified Purchase
Buyer beware! Don't believe the hype. This thing is not worth 4 stars. For the price, it *is* a very inexpensive and feature-rich mp3 player; however, it lacks or poorly implements some critical features that any mp3 player needs to handle well in order to be useful - no matter the price.

In the end, I've had to look for another player. I'm out the 25 bucks I spent on this thing. That makes it pretty expensive!

The short list of critical features it is missing:
- Overall, not enough buttons for its functions. All buttons share multiple functions which are not grouped intuitively. Lots of functions take long-presses of varying periods of times. It's like learning Street Fighter or something.
- No direct volume control. The actual process is comically cumbersome and involves hitting buttons in the right order - see the point above
- File/track sorting is very broken, so albums play out of order. Specifically, the sequence: "01-<name>", "10-<name>", "02-<name>".. happens on every album. Was this device never tested with albums with more than 9 tracks?
- No ability to easily switch between albums. They could easily fix this by making "next track" at the end of one album play the beginning of the next album in the library, but sadly this is not the case. Instead, it just repeats the whole album.
- Track grouping is poorly implemented. Lacks the ability to group albums by artist. You can group them in folders when copying, but they don't display that way. Instead, you can either: a) Browse all albums from all artists in a flat listing which lacks the name of the artist on the albums, or b) Browse all *songs* by an artist across all albums - with the broken sorting listed above (presumably, I'm supposed to listen to the first track of every album, then the 10th!)

The only use case I see for this device: someone who has no more than a few dozen or so songs that they listen to at a time, and don't care what order they play in. Beyond that, even $25 is too much money for a device that I simply can't use.

1.0 out of 5 stars If you don't want to use an MicroSD it's fine
Reviewed in the United States 🇺🇸 on May 27, 2019
Color: BlueCapacity: 8 GBVerified Purchase
I don't know why people are do happy about this product except for its cheap price. The instructions are so basic they are almost not helpful. It's as if someone says "How do I make my car go" and someone asks "By starting your car." If we knew how to start our car we wouldn't be asking how to do it. That's how it is with this device. The MicroSD card didn't work at all. I was able to put LOTS of mp3 files on it. I have a Mac and I just used it like a flashdrive. I spent lots of time putting audiobooks and podcasts in folders. I even put some of those folders within other folders to categorize them. Are they on the Ruizu? Yes, but--- First off anything you put on the MicroSD card can only be accessed through the 'Folder' icon. Inconvenient, yes, but not a dealbreaker. Here is the next inconvenience--When you select the 'Folder' icon you then have two choices 'Local folder' and 'Card folder'. [You only have these two choices if you've installed a microSD card.] Everything in the 'Local folder' plays fine. Everything in the 'Card folder' does not play fine. In fact, it doesn't play at all. Worse--it just freezes and no matter what button you push nothing happens. Frozen screen. You have to physically turn the device off and turn it back on.
So this player is useless to me. I wanted something to store lots of audiobooks on it so I didn't have to store them on my phone, but with only 8GB of storage (without the SD card) I might as well have put it on my phone.
The sound is good and although the navigating with the buttons isn't as easy as a smartphone would be, they are still reasonable for such an inexpensive device.
Photos? What a waste of this device. It's not a good screen for viewing photos, calendar, games, video, or anything. The screen should be used only for viewing the titles of the audio.
It's small light and cute but for me not being able to have a usable MicroSD card made this whole device pointless. The company is very responsive to email but not very helpful understanding problems or fixing it but they did refund my money easily.
I don't recommend this product if you're going to use an SD card. It just won't work. Either mine was defective (although the company didn't say that was the problem) or all the other people who love it never use an SD card.
